Kangen Water™ is the brand name of alleged health-enhancing alkaline water that is created through the process of electrolysis. Electrolysis separates "normal" tap water (H2O) into two parts: acidic H+ molecules and alkaline OH- molecules. Kangen Water™ advocates believe that the pH level of the body's internal fluids affects every living cell in the body, and that over-acidification of the body may lead to chronic diseases.
In the article "The Positives and Negatives of Ionized Water," reporter Laura Johannes discusses the increased interest in water ionizers in the United States.
"Human evidence is lacking, safety profile is lacking and it's very expensive," Dr. Catherine Ulbricht, Founder and CEO of Natural Standard, told The Wall Street Journal.
Many controversial laboratory studies and positive anecdotal reports have been published in Japan and Korea attesting to the health benefits of ionized alkaline water in humans and animals. Reports range from the successful treatment of skin conditions with alkaline water, to the treatment of gynecological conditions, heart disease, weight problems, premature aging, diabetes, allergies and cancer. However, credible scientific evidence is lacking to support these claims.
